Anyone seen this guitar on eBay, looks nothing like any ObG firebird I've ever seen. So many things wrong with it for an Orville looks very much Korean built to me. May well be a nice guitar as you certainly don't come across many neck thru firebirds but I'd certainly have doubt's it a legit Orville , prototype or not.

I see that's now up to over $1000 and not hit his reserve price. Gotta say I'm a bit surprised people have gone so high for a guitar with no provenance and Korean looking serial. But I suppose neck thru firebirds are a rarity and if you have chance to play before you bought it may be worth the risk.
